1. Rock Cycle

2. igneous rock, sedimentary rock, and metamorphic rock.
- Classifying Rocks
Rock Classification
Geologists classify rocks into three major groups depending on how they are formed:
igneous rock, sedimentary rock, and metamorphic rock.

3. Rock Processes Review
Igneous
Sedimentary
Metamorphic

4. 5. Igneous Rock Serve and Enjoy
Igneous Rock Recipe
1. Take some Minerals & Gasses – Mix well
Place in oven (2,000 C) Add Heat Energy & Melt
Quartz Biotite Feldspar
3. Change Rock to Liquid Phase (Magma)
4. Remove from heat, let it Cool & Crystallize (Intrusive/Extrusive)
5. Igneous Rock Serve and Enjoy
Minerals
+ Heat

5. Sedimentary Rock Recipe
1. Start with existing rock at the Surface
2. Weather (Break Up)
3. Erode (Carry Away)
4. Sedimentation & Deposition
5. Compaction & Cementation
Igneous Rock
Sedimentary Rock

6. Metamorphic Rock Recipe
1. Get some pre-formed rock – Igneous or Sedimentary will do & burry it deep underground.
Granite
(Igneous)
2a. Add a mild amount of Heat
(Not too hot)
2b. Squeeze to Foliate
+ Pressure
+ Pressure
3. Cool & (Re)-Crystallize
Gneiss (foliated)
+ HEAT
Note: Add more heat for Igneous Rock

Change to Liquid Phase (Magma)
Weather (Break Up)
Erode (Carry Away)
Take minerals & Add a lot of Heat to Melt
Sedimentation & Deposition
Metamorphic Rock
Compaction & Cementation
Cool & (Re)-Crystallize
Sedimentary Rock
Add Heat & Pressure
(Not too hot)
burry it deep underground

13. What is the Rock Cycle? -The process of rocks changing from one
type of rock to another
Igneous Rocks
Any rock type can be changed into any of the other
two and back again depending on conditions
Sedimentary Rocks
Metamorphic Rocks

18. mtn’s are granite= Igneous
The rock cycle is an active process that you can see just about everywhere outside:
The white tops of these
mtn’s are granite= Igneous
Weathering & Erosion are actively breaking
down the mountains & creating sediment
Deposition:
minerals from the Granite
spreading out as sand & clay!
This makes the soil of the valley
Underneath the surface,
sediment is being compacted
& cemented = Sedimentary
